Last week the injury-plagued Englishman was No. 169 in the world, his worst ranking in 12 years. But after his impressive come-from-behind, three-shot victory at Carton House, Casey is now No. 102, the biggest mover of the week.
Bill Haas’ victory at the AT&T National didn’t have nearly the same kind of impact in the rankings, rising only from 29th to 24th. He joined Dustin Johnson, Phil Mickelson and Justin Rose as the only players to win in each of the past four seasons.
The top 10 had only one minor fluctuation: world No. 1 Tiger Woods, Rory McIlroy, Justin Rose, Adam Scott, Matt Kuchar, Phil Mickelson, Brandt Snedeker (from No. 8), Luke Donald (from No. 7), Graeme McDowell and Louis Oosthuizen.
